城乡“安全健康单元”营建体系与应对策略——基于对疫情与灾害“防-适-用”响应机制的思考

CONSTRUCTION SYSTEM AND STRATEGY OF “SAFETY AND HEALTH UNIT” IN URBAN AND RURAL AREAS: BASED ON A RESPONSE MECHANISM OF “PREVENTION-ADAPTION-UTILIZATION” FOR COPING WITH PLAGUES AND DISASTERS

针对"小概率-大代价"的疫情与灾害发生,提出了建立"防-适-用"响应机制的理念,解析了城乡建设的"安全健康单元"的概念,诠释了其基本内涵、营建目标、运维机制,以及与既有城乡空间的关系,明确了"安全健康单元"的核心内容、营建策略、关键技术等,为人居环境营建的发展提出了新思路与新举措。

"Small probability–big loss" is the main characteristic of plague and other disaster outbreaks.Aimed at this,this paper establishes a response mechanism of "prevention-adaption-utilization" to cope with the outbreaks.It proposes the conception of "safety and health unit" by exploring its connotations,objectives,operation and maintenance mechanisms,and its relationship with the existing urban and rural spaces.It also specifies the main components,construction strategies,and key technologies of the "safety and health unit",in the hope of providing new thoughts and measures for the construction of better human settlements.
